Abstract

A time-gated global shutter SPAD-based QVGA image sensor is employed as a quanta image sensor (QIS). QIS behaviour is experimentally demonstrated. Real-time temporal oversampling of time-gated images is implemented, facilitating two-bin indirect time of flight (ITOF) imaging with and without background rejection achieving worst case 38mm RMS precision in 600mm dynamic range.
